The first year or so we lived in this house, the water softener worked fine and used about 1 bag of salt per month. This past summer, after dishes not getting cleaned properly in the dishwasher I realized there might be a problem with the water softener and that we hadn't needed to add salt in a while. It had formed a salt bridge, which we attended to with a broom handle according to instructions found from various sources, and water quality and cleaning went back to normal. Since then, salt bridges have been forming on a regular basis. It's a Kenmore softener, and according to the writing on the cupboard door next to it, was installed 7/02, so theoretically it's just over 5 years old. Any idea why the appliance is now forming these salt bridges regularly, and what to do to get things working properly again?
Thanks for helpful suggestions,
Karen
